[QUOTE=unconnected;457087]127^121+121^127 is already factored, please remove it from 15e queue[/QUOTE]

Yes, that was my error. I've alerted Fivemack and Greg via PM. Apologies to all.

C206_149xx041_13 relations trashed
 
The .fb file has two sets of R1/R0 which appears to have caused havoc on the relations. They all come up as error -11. It looks like it needs to be corrected and re-sieved.

C206_149xx041_13 relations may be good

All is not lost. The .poly file appears to be correct. I removed the incorrect values from the .fb file and post-processing is running normally.

Queued up C210_135_71, C183_705670360649_19, C211_134_116 on 14e

Many thanks to everyone who has posted yield numbers to save me the fuss of trial sieving :)

pinhodecarlos 2017-04-28 21:05

Do we have more candidates to feed the 14e and 15e grid? Just wondering due to the upcoming BOINC Pentathlon, disciplines will be soon known.

Two more for 14e
 
C196_122_115 and C195_148_98 are ready for NFS using 14e, having survived a full t55 from yoyo@Home, plus a few thousand more curves @B1=3e8 by me.

[QUOTE=pinhodecarlos;457826]Do we have more candidates to feed the 14e and 15e grid? Just wondering due to the upcoming BOINC Pentathlon, disciplines will be soon known.[/QUOTE]

What's the timeframe? I have several more candidates for 14e and 15e but they do need more ECM before SNFS so I will need to repoint assets to prepare.

Where and when are the projects announced?
5 days (Marathon, Swimming, City Run, Cross Country) or 3 days (Sprint) before the start of each discipline on the main page, via Blog, RSS feed, Twitter, and Facebook. While the Marathon project is announced exactly five days in advance at 0.00 UTC, the announcement of the other projects are possible at 0.00 UTC, 6.00 UTC, 12.00 UTC, or 18:00 UTC to compensate for geographical advantages. Regardless of the time of the announcement, all disciplines start and end at 0.00 UTC.

From here: [url]https://www.seti-germany.de/boinc_pentathlon/27_en_FAQ.html[/url]

swellman 2017-04-28 21:47

Well the 15e queue seems loaded with work, and I doubt even the BOINC Pentathlon will drain it.

I'll try to prepare several (4-5?) more 14e candidates for consideration.


All times are UTC. The time now is 23:12.
